I'm updating from cios rev14 to 20, and I have ios58 installed, but it won't let me choose ios58 as a base. I read somewhere that you can rename ios58 to appear as ios57, and install to rev20. Could someone elaborate on this method? My wii is fully hacked and up to date with ios's, and I just heard that 58 is the best base to use. Any help would be much appreciated.
